Russian diamond rough (sawable) 0.509ct rough (trigon)
Among the many gemstones, diamonds are a special stone. There are several names for rough diamonds depending on their shape. This is a sawable rough stone, which is said to have a particularly beautiful shape. It is a regular octahedral rough stone that looks like the base of a pyramid attached to the ground. It comes in a wide variety of transparency and colors, and I hear there are collectors of it. Enjoy the beauty of its natural state. It is a sawable diamond equivalent to VS-SI class. There is also a trigon. It is a sawable diamond of a size of over 0.50ct, which is quite impressive.
